Journal Title: International Journal of Ayurveda and Pharmaceutical Chemistry - Year 2018, Vol 0, Issue 0
Abstract
Asoka - Saracaasoca (Roxb.) de Wilde is a well-known drug for the herbal industry. Even though various parts of this plant owe numerous pharmacological actions, its classical officinal part is stem bark. Due to over use and irrational collection practices the stem bark of this drug has been severely adulterated in the drug market. In Ayurvedic classics, the stem bark, are proposed to be collected during Saratritu (autumn season). The drug material to conduct the study was collected during the very same period. A lot of studies have been published about the phytochemistry of this drug, but none of them strictly followed this type of collection practices. This emphasizes the uniqueness of present work. Physicochemical parameters such as total ash, acid insoluble ash, water insoluble ash, moisture content, fibre content, tannin content, phenol content of the sample of test drug are estimated and found to be similar with that of the description in API. Sugar content in the drug is very trace, so as to quantitatively estimate the total and reducing sugar. The prepared kashaya was slight acidic in nature, by using the digital pH meter and it was found to be 6.56. The extractive values such as cold alcohol soluble, hot alcohol soluble, cold water soluble and hot water-soluble extractives of the drug sample were estimated. The observed values were found to be within the range as that of API. This work tries to merge up the ancient wisdom with modern techniques of phytochemistry.
